TIG Why constantly to use the method of group_miner, when in him practically is not there a necessity? Why to apply properties to entity, when are new properties of entity equal to the applied properties?These questions are linked at a speed of implementation of script on the large scenes.

Example of considerable increase of speed of implementation of script:

Thanks Alex - you've probably noticed I used the .is_a? test everywhere else in the script - however, I didn't realise it was so much slower to use typename=="". I've also incorporated my own version of your group_miner speed-up suggestion that now avoids testing groups that area already unique...

I just need to edit ALL of my other scripts to change e.typename=="" to e.is_a?() !!!

I have lost a component somewhere in my drawingto find it, I pasted a second one in a visible placewhen I select this, the entity info clearly says Component (2 in model)with the components window context menu, I selected all componentsI thought then, if I could hide the rest of the model, I would easily spot where the original one isbut view/hide rest of model doesn't work unless you are inside the component,which means you can select only one of both, and the other one is deselectedplease helpFrank

View > Hidden Geometry ON will show all hidden objects.If it's on a Layer that is OFF you won't see it though...The Outliner will also show all instances that are on ON Layers...You can select them in the Outliner and they select in the model.
